无线Ad Hoc网络拓扑控制研究

Research on Topology Control in Wireless Ad Hoc Networks

由节点位置和传输范围确定的无线网络拓扑结构对网络性能有着重大影响。拓扑控制通过调节节点的传输功率,能够优化网络的性能,减少节点的功率消耗,延长网络的生存时间。拓扑控制算法按其优化目标可以分为基于几何结构和基于能量有效性2类,前者主要以某些几何结构为基础构建网络拓扑,后者主要关注网络的能量有效性。文中综述了Ad Hoc网络拓扑控制的研究现状,介绍了一些典型拓扑控制算法的原理及最新进展。

The topology of a wireless Ad Hoc network,which is determined by nodes positions and transmission ranges,has a significant effect on network performance.By adjusting the transmission powers of nodes,topology control is capable of optimizing network performance,reducing energy consumption and increasing network lifetime.Topology control algorithm can be divided into two categories according to optimization goal: geometry struction and energy efficiency.The former constructs the network topology on the basis...
